will you help my mommy please..

Hi my name is Lilly..I am a 15 month old chorkie..A little over a month ago ago i couldnt walk anymore.My mommy rushed me to the puppy doctor and found out I have a birth defect in my spine.As I grew up my disks started not connecting to my spine as well..So now my left back leg is stiff and my left front leg just curls under me.My mommy has spent every dime she had to get me better..But the doctor says I need MRI and stem cell treatments.. possible  laser treatments and if those dont work then surgery ..I really want to walk again.I miss running and playing with my brother and sister..It makes me so sad when I see them chasing the ball and I cant get up and join them.I cant even go potty by myself anymore..mommy has to hold me up..Can you please help my mommy and  I???
